If the pillow is not suitable, it will cause cervical vertebra pain, insomnia and dreaminess, and fatigue the next day, which will affect the normal life the next day. However, it is extremely difficult to choose a suitable pillow because of each person's body curve, sleeping posture and other factors.

Since the suitable pillow heights are different when people lie on their sides or supine, there are some pillows on the market that can automatically adjust the height according to different sleeping postures. The pillow depends on the inflation and deflation of the airbag to change the height of the pillow. However, since the airbag expands in the vertical direction and contracts in the horizontal direction after inflation, a gap will be formed between the airbag and the cavity in which the airbag is placed after inflation. Once the head and neck of the human body are located in the gap, a sense of collapse will occur, which is very uncomfortable.

DETAILED DESCRIPTION

The specific implementation method of the utility model will be further explained below, but the specific implementation method of the utility model is not limited to this.

EMBODIMENT 1

Referring to FIGS. 1 and 2, a pillow with adjustable height comprises a pillow body 1 and an airbag 2; The pillow body 1 is internally provided with a cavity for accommodating an airbag 2; The airbag 2 is arranged on the lower bottom surface of the cavity and expands towards the direction close to the upper top surface of the cavity after inflation;

The pillow body 1 extends to form an arc-shaped transition region at the connecting part between the side wall of the cavity and the upper top surface toward the direction close to the cavity. As a simple replacement of the embodiment, the transition region can also be rectangular. As long as the transition region is thickened, the effect of the embodiment can be realized. Therefore, the scope of protection of this patent cannot be limited by this.

In the above-mentioned pillow with adjustable height, an arc-shaped transition region is formed by extending the connecting portion between the side wall of the cavity and the upper top surface of the pillow body 1 toward the direction close to the cavity. Thereby increasing the thickness of the transition region of the pillow body 1 between the side wall and the upper top surface. When a person lies on his back, the airbag 2 shrinks, the supporting strength of the cavity becomes smaller, and the head or neck easily collapses the cavity to form a collapse feeling. After the design of the present utility model is adopted, the supporting force of the cavity can be increased to reduce the collapse feeling. In addition, when lying on one's side, the airbag 2 expands in the vertical direction and contracts in the horizontal direction. When the airbag 2 is propped against the upper top surface of the cavity, a gap will be formed between the airbag 2 and the side wall of the cavity. Once a person's head is located in this gap, a sense of collapse will occur, which is not comfortable enough. After the design of the present utility model is adopted, when the airbag 2 expands and contracts along the horizontal direction, the contraction amount of the airbag 2 can be compensated because the transition area is relatively thick, so that the airbag 2 and the transition area maintain a fitting state, the generation of gaps is avoided, the generation of collapse feeling is also avoided, and the comfort level of users is increased.

In this embodiment, the airbag 2 is a plurality of sub-airbags connected in series.

Further, in order to form the air cavity in this embodiment, the pillow body 1 includes an upper half part 11 and a lower half part 12; The upper half part 11 and low half part 12 are spliced oppositely to form the cavity and the sub-cavity; An electrical circuit assembly is placed in the sub-cavity for controlling the inflation and deflation of the airbag 2.

The upper half part 11 is divided into a neck support area and a head support area, and the sub-cavity is located on the side of the head support area away from the neck support area. In this way, the sub-cavity can be kept as far away from the head of the human body as possible, thus preventing the noise made by the air pump from affecting the sleep quality of the human body.

With further reference to FIG. 3, the lower half part 12 has a height adjusting cavity 122 for adjusting the overall height of the pillow body 1, and fillers cooperating with the height adjusting cavity 122. The fillers are filled into the height adjusting cavity 122, and when the filling height of the fillers is higher, the height of the corresponding height adjusting cavity portion in the pillow body 1 is higher. For example, the height adjusting cavity 122 is arranged at a position corresponding to the head support area, and the height of the head support area can be adjusted by adjusting the number of fillers.

In this embodiment, the pillow body 1 is made of sponge material, and the filler for filling the height adjusting cavity is also a sponge block. The sponge block can be a plurality of blocks, and the user can select an appropriate number of sponge blocks according to actual needs.

With further reference to FIG. 4, one end of the lower half part 12 near the neck of the human body extends outward from a platform 121; The platform 121 extends along the length direction of the pillow body 1 and is located in the cavity formed by the neck, shoulder and back and the human body support when the human body is supine; The platform 121 is provided with pressure sensors 123.

In this embodiment, the pressure sensors 123 are arranged at intervals on the lower surface of the platform 121 along the length direction of the platform 121. The sleeping posture of the human body can be distinguished by the pressure distribution of the human body on the platform under the supine and lateral lying states.

Finally, referring to FIG. 5, in this embodiment, the upper half part 11 is provided with a detachable support piece 111 on the outer surface of the neck support area, and the user adjusts the height of the neck support area.
